Man accused of abducting baby in Sydney turns himself into police

A 24-year-old man wanted for allegedly abducting his 16-year-old ex-girlfriend and their eight-month-old baby in Sydney has handed himself into police.

He was arrested and subsequently charged with a number of offences.

The man allegedly forced his way into a house in Chester Hill in Sydney's west last Thursday and abducted the girl and baby at knifepoint.

The girl was later released and the child was handed to police by a relative the following day.

Police spent nearly a week searching for the man before he turned himself into Bankstown Police Station late last night.

"He was arrested and subsequently charged with a number of offences, including take and detain person with intent to obtain advantage and take or detain child with intent to remove from parental control," police spokeswoman Felicity Jenkins said.

The man has been refused bail and will appear in Bankstown Local Court today.
